Android XML Parsing Using DOM Parser

I have below xml file.Now Get Data from xml file using DOM Parser.

<?xml version="1.0" encoding="utf-8"?>
<rss>
<item>

<id>1</id>
<title>Image 1</title>
<desc>Whether it's made with soy byproducts, milk, or clay, these natural wall color options are healthy for your home.</desc>
<pubDate>22/03/2012</pubDate>
<link>https://www.dropbox.com/s/jpqsvse4xx9qt96/image1.jpg?dl=1</link>
</item>

<item>
<id>2</id>
<title>Image 2</title>
<desc></desc>
<pubDate>23/03/2012</pubDate>
<link>https://www.dropbox.com/s/n29704f65zigty7/image2.jpeg?dl=1</link>
</item>

<item>
<id>3</id>
<title>Image 3</title>
<desc></desc>
<pubDate>27/03/2012</pubDate>
<link>https://www.dropbox.com/s/1l3qoojbi4drqsd/image3.jpeg?dl=1</link>
</item>

<item>
<id>4</id>
<title>Image 4</title>
<desc>Natural paints are generally more expensive than conventional paints and arenĂ¢€™t always widely available, but can be ordered online.</desc>

</item>
</rss>

now above xml file have item tag is Nodelist.and child nodes are id,title,desc,pubdate,link.
NodeList nList = doc.getElementsByTagName("item");
you can get length of nodelist using getLength.and retrieve one by one child nodes.


for (int temp = 0; temp < nList.getLength(); temp++) {
Node nNode = nList.item(temp);
           Element eElement = (Element) nNode;
 }


now using  eElement you can getvalue of nodes
private static String getTagValue(String sTag, Element eElement) {
NodeList nList = eElement.getElementsByTagName(sTag).item(0) .getChildNodes(); if (eElement.getNodeType() == Node.ELEMENT_NODE) {
if (nList != null && nList.getLength() > 0) {
            return nList.item(0).getNodeValue();  
}
} return null; 
  }
